. The total linear momentum of a bus of mass 4000 kg that is moving at a speed of 25 m/s and a truck of mass 2000 kg that is moving at a speed of 20 m/s is kg - m/s. a 220000 b 140000 C 180000 d 80000 6 120000

the answer is c.)

explanation:

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
